SPECIFICATION forming part of netten Patent No. 357,079. dated February 1. 1887.

Application tiled January 16, 1886. Serial No. 188,725.

To all whom vit may concern:

Be it known that we, HARRY B. GLEAsoN and WILLIAM H. H. OLAGUE, residing at Rochester, in the county of Monroe and State of New York, have invented certain new andI useful Improvements in Fire-Place Heaters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to fire-place heaters intended for dwellin g-houses, school-buildin gs, public halls, stores, ofces&c.

The invention consists in a lire-place having a depressed fireepot and grate, a fuel-feeding I5 apparatus and ash-pit extending below the floor of the room, and special connections by which steam and hot air may be used in heating, all substantially as hereinafter pointed out and claimed.

In the drawings, Figurel is a vertical lon gitudinal section about midway, looking from the front to rear of the re-place, showing the general level of the parts with relation to the floors of the building, the lifts, the flues, and 2 5 the tubing system for the water-heater. Fig.

2 is a rear view with parts of the hot-air apparatus removed and part in section, showing rear of water-back andthe general arrangement of parts, as in Fig. 1. Fig.3 isa vertical cross-section on broken line w Fig. 2,-

showingthe fire-place and water and air heatking apparatus and connections to the various rooms or fioors, and showing also the ash-pit and draft-regulator. Fig. 4 is a front perspec- Fig. 5 is a rear perspective of the water-sections with parts broken away and thrown apart to show thev flue-passages through and in rearof the waterback, the lower repotsections being in contact. Fig. 6 is a perspective showing the grate/ and its operating mechanism detached. Fig. 7 is an enlarged perspective showing the mouth of the chute, hereinafter referred to, and the agitator. Fig. 8 is a detail plan showing how the air-dues are completed.

The numeral 1 indicates the ash-pit, which is preferably in the cellar or basement of the house, and is inclosed, so as to be free from danger and to prevent the escape of dust and 5c ashes. A door, 2, provides for the removal (No model.)

of ashes. The ash-pit may be provided with a screen forthe ashes. A damper-door, 3, 'ust below the grate 4 4 serves to admit air tov4 support combustion, and is dmanipulated by rod 3X, or from below. The grate 4 4 is supported below the level of the main Iioor 5, and is connected with shaking apparatus above and below` said floor.

The fire-pot 7 7 is preferably in horizontal sections, as shown, each section being a complete water-box and connected with hot-water or steam radiators, and also preferably with the water-back sections 8 8, Snc.,- by a manifold, 9, and pipes, as 10, leading to radiators in various parts of the house. The main iloor may be heated by a radiator or stack, 11, conveniently arranged under iioor 5 and connected with the water hre-box by pipe 13. The usual arrangements for securing watersupply and hot-water or steam circulation may be adopted, the same forming no part of the present invention. A shield or grating, 6,` prevents the escape of coal at the front of the fire-place.

The watersections 8 8 are hollow, prefer-4 ably of cast metal, and form the back and sides of the fire-place proper. The face toward the fire forms a parabolic radiator or reflector provided with fines or passages 14 14, &c., through which the smoke and products of combustion pass. These passages 14 are simply arched recessesin the shell of the various sections forming the water-back, and the shell of the sections thus presents an enlarged or corrugated surface to the contained fluid. 85 The passages 14 are continued up the back 4of the water-sections 8 8, Snc., the back passages 15 15 being preferably inclined alternately toward the sides, so that therear dues correspondingly-corrugated rear plate, or each l iue may be completed separately, or a dat plate applied in the rear of the water-back to inclose and complete `the flues in half-round form. The flues are continued upward at 17 through the hot-air chamber 20 to the chim- Ioo ney-flue 21, and the fines 16 16, &c., from the fire-pot sections 7 7 are carried in rear of chamber 20, which chamber 20 is thus made a hot-air chamber surrounding the water tirebox and water-back, and being itself nearly or quite inelosed by smoke-fines, as well as being traversed in its upper port-ion by smokeflues.

A damper, 22, over the smoke-dues maybe shifted so as to regulate the draft in usual manner.

` The hot-air chamber 20 has passages or hotair fines 23 leading upward at the sides of the smoke-due 21, and these flues are provided with side passages, as 25, and registers, as 26, at such points in the upper rooms as may be desirable. rlhe hot-air fines also conveniently contain the hot-water or steam pipes l0.

Air to supply the hot-air system enters from the cold-air box 2S, or from the outside of the building, and passes around the water firebox and water-back, receiving its heat by radiation from the hot water rather than from the burning coal. A damper, 29, serves to regulate the supply of cold air which can be introduced to be heated and passed upward.

The lower fire-pot section, 7, resting on the masonry A, forming the inclosure of the ashpit, is firmly supported, and makes a solid foundation for the remaining fire-pot and water-back sections. rllhe sections are each complete, and the corrugated walls of the sections l'orm the smoke-passages, so that there is no necessity for the insertion of tubes through any section, yet a large heating-surface is provided.

The fire-pot being sunken below the iloor, may have a grate of any convenient size without encroaching on the available space in the room to. be heated. The fire-pot is preferably enlarged at its lower end, giving enlarged grate-surface and insuringa steady downward feed of coal in the iire-pot.

The air to support.combustion is furnished from the cellar or basement, or from the out- Side of the building, and is not withdrawn from the room B above floor 5. So the air in cold-air box 28 is preferably furnished from the basement, as at 29, or fro'm outside, and maybe partly warmed by contact with hotwater pipes before entering the hot-air chamber 20.

The passages 36 30 at each side of the ashpit serve for the reception of coal-lifts 3l, which are hung on chains or cables 32 ,passing over pulleys, as 33, and counterweighted, as shown at 34; or the coal-lifts 3l may be raised in any other manner common to dumb-waiters.

The bottom 35 of the lift 3l is hinged, and when the lift is on a level with the inclined passage 36, leading into the fire-pot, the bottom may be tripped, so that the coal in the lift will feed down the inclined passage 36 into the.

tire-pot. The bottom of the coallift being a little wider than the passage 30, will not open, except when the lowerend of the lift is above the passage 36, when the edge of the bottom piece, 35, will rest on the plate forming the bottoni of said passage, thus making a chute. The bottom 35 should be held closed by gravity-catch when the lift is lowered,whieh catch will be unclasped when the lift is raised into position to feed down the chute 36.

An agitator or stop, 39, at the mouth of chute 36 serves to cut off or increase the supply of coal through said chute. Thisagitator may be simply a swiveled bar with teeth thereon, and may be turned by a handle or key.

Partitions 3T cover the top of passages 30, so as toY prevent the upward passage of cold air to fines 23.

Suitable doors at the bottoni of passages 30 provide for the filling ot' the liods or lifts 3l.

A recess, 40, just below the mantel 4l,forms a receptacle for a curtain, 42, of asbestus or iiexible metal. This curtain winds on roll 43, and may drop down in front of the fire to serve as a blower,7 or draft-regulator.

rlhe grate-sections 4 4 rock on journals 45, and levers 46 from said journals are joined by rod 47, and a pitnian, 4S, connects the rod with lever 49, which has its fulcruin at 50, and can be moved by handle 5l, or the removable handle 52, working through a slot, 53, in the door 5.

As has been explained, this fire-place heater derives its air for the support of combustion and for heating the chambers from asource outside the room in which the open fire is located. Consequently the air in that room is not rarefied or vitiated by overheating, while by means of the water system the distant portions ofthe room may be heated, thus producing an equable and healthful temperature throughout the room. The products of combustion pass first through thepassages in the water-sections,thus imparting the first fierce heat of the fire to the water, so that the heat may be utilized to best advantage. After the smoke and gases have thus passed through the water-sections they come in contact with the walls of the airheater and heat the air therein without ex posing it to such an intense heat as to deprive it of its oxygen. rllhe radiation from the watersections also helps to heat the air, which is thus tempered to better advantage than is usual with hot-air heating apparatus.

rlhe mechanism for feeding coal to the grate admits of the utmost cleanliness, as no coal need be carried through the room in which the mantel and the fireplace are located.

The sunken fire-pot secures a heating of the air strata near the floor of the room, and the parabolic face of the water-sections tends also to direct radiation of heat forward. and well down in the room.

The fire-pot, being entirely below the level of the floor, can be quite surrounded by the water-chamber without closing the open front of the fire-place. All the surplus heat of the fire-pot can thus be absorbed, and the build- I OO IIO
